Description: The 1L222 Avtobaza is a truck-mounted radio-electronic countermeasure system intended to jam airborne radar systems thus preventing air strikes. Acting as a passive radar system it is able to track airborne targets at ranges of up to 150 kilometers. In October 2011, Russia handed over several Avtobaza truck-mounted systems to the Islamic Republic of Iran. The 1L222 Avtobaza defense systems can be deployed to protect Iran's nuclear facilities from aerial attacks.
In November 2011, a US Air Force RQ-170 Sentinel went missing in Iran or near Iran's border. Iran claimed that the unmanned aircraft was shoot down by its air defenses while NATO stated that the aircraft suffered a malfunction. The Sentinel was recovered by Iran with little damage to its airframe and its sensitive electronic surveillance package. Some sources especulated with the possibility of the aircraft being highjacked or jammed cutting the communications the aircraft's control station by the Russian-made Avtobaza electronic warfare system delivered to Iran that same year. On December 8, 2011, Iran released a video with the RQ-170 unscatched proving that the aircraft had been highjacked by electronic means. In March 2014, the Russian military using the Avtobaza intercepted and grounded a US Army MQ-5 flying over Crimea.
